i have a 2013 ford expedition and im planning to install 9.00 17R sand tire's which has a circum of 856 mm.
my truck came with 275/55/R20 tires and im running 275/60/R20 for a year now and i felt a little difference when shifting and downshifting, so im assuming that im gonna need to calibrate when installing the sand tires and i have tried using Forscan but the Bdycm doesnt show.
the reason im installing sand tires is because i live in Saudi Arabia and i go to the desert a lot.
any ideas on how to recalibrate?
